Sorry Marten

we do not have them as group (we borrow it often) and if I had one I surely wanted to keep it ;-)

Good luck

Marten Geertsema

jammer - they are pretty cool

Haifei Liu

Sorry, Marten.

I borrowed the one from ISTerre Lab in Grenoble

Check out open-source DC software:

http://simpeg-dc.readthedocs.org/en/latest/

You can run 3D forward modeling and inversion with this.

Dale F Rucker

Check out R.T. Clark. They usually have some resistivity gear for sale.
